taken by himself in Amdo. M. Alpheraky (Eom. sur Lep. v. p. 118) describes 
two varieties of this species, viz. var. ordossi and var. evanescens, discovered 
by M. Potauine in North-western China. 
Coenonympha semenovi. (Plate XI. tig. 4, s .) 
Ccenonympha semenovi, Alpheraky, Rom. sur Lep. iii. p. 405, v. pp. 82, 118, pi. iv. 
fig. 7. 
" Supra dilutissima brunnea ciliis albidis, ^ alls anticis orbiculo (puncto) apicali albido, postica3 
serie antemarginali orbiculoruni albidorum, 5 supra dilutior, orbiculis vix couspicuis ; subtus 
anticfe ut supra, posticarum. pagiua interna virescenti grisea, externa maculis magnis orbi- 
culisque antemarginalibus albis." (Alpheraly, I. c.) 
Expanse 25-26 millim. 
M. Alpheraky records the species from Tsaidame on the Bourkhane- 
Bouddha range, and from a place between Tcha-tchi-kou and Tchangla. 
Occurs in Western China at Ta-chien-lu and Pu-tsu-fong in July, and at 
How-kow in Thibet in July and August. In the latter locality it is found at 
an elevation of 10,000 feet, and in the other places at about 7000 feet. There 
is very little variation, but one of my female specimens agrees with the male 
in colour. 
M. Grum-Grshimailo has sent me examples which he took in Amdo ; these 
are rather paler than my Chinese specimens. 
Coenonympha typhon. (Plate XI. fig. 3, var.) 
Papilio tiphon, Rottemburg, Naturf. vi. p. 15 (1775). 
Papilio davus, Fabricius, Gen. Ins. p. 259 (1777). 
Var. tydeus, var. nov. (Plate XI. fig. 3, J .) Pale fulvous, usually without markings, but one of the 
specimens has a small subapical black spot indistinctly ringed with paler ; the under surface 
is very similar in colour and marking to pale forms of the species from the Alps, but the pale 
band of secondaries is more broken, and its middle portion represented by a longitudinal bar. 
The sexes do not differ iu colour or marking. 
Expanse 38-40 millim. 
Occurs commonly at How-koAV, Thibet, and flies in Jidy and August at 
an altitude of 10,000 feet. 
In Northern and Central Europe this species frequents mountain meadows 
and moorland. It is local, but common where it occurs. There are several 
named local races, one of which {isis, Thnb.) is recorded from Lapland and 
the Amur (Menetries, in Schrenck's Eeisen, p. 43. no. 84).
